Dolly go round

Yet another outing for that Gaelic icon, Dolly Parton, on BBC Alba at 2300 last night.  Yes, the one recorded at the 02 in 2008, and shown three times previously on the channel.  And three times on BBC Four.  Any chance of some viewing figures ?   Is this the right way to double the number of young Gaelic learners in primary schools (to 800), as apparently required to prevent the language dying out ?
